Fuel EX

Any trail, any time

Fuel EX is made to hit every trail, every day. With a balanced trail bike geometry and refined suspension, Fuel EX is fast on singletrack, capable in the rough and fun wherever you ride it. There's no fancy mixed wheel set-up. No complicated suspension dials. No confusing parts that you have to tinker with before every ride. It’s just an outstanding trail bike that works for everyone.

If you’re going to get just one mountain bike, make it this one.

'Perfect all-rounder'


Off-the-shelf suspension is an off-the-back idea

Bike brands often take the easy trail when it comes to mountain bike suspension. Rather than developing a shock that elevates your ride, they’re just choosing one that fits (and elevates their profit margin, probably).

We take that personally. And you should, too. Because when it comes to your experience on the trail, suspension is everything. That’s why we design custom solutions from our Suspension Lab in California that work seamlessly with Trek frames to give you the best possible experience on the trail.


Most bike brands use off-the-shelf suspension, which means that they take the easy route and spec a trail bike with a shock that already exists and happens to fit the frame.

Okay, okay…

A handful of brands use tuned suspension – which means that they take an off-the-shelf shock and make some basic tunes. It’s better, but not the best.


We partner directly with industry experts like Fox and and RockShox to create unique suspension solutions made and customised for your bike and the way you ride it.

The shock that can keep up

Fuel EX features Trek’s exclusive RE:aktiv damper, which is firm when you’re pedalling but instantly gives way to soak up bumps. Want to take things from ultra-responsive to ultra-mega-responsive? Select models feature RE:aktiv with Thru Shaft, which reacts to terrain faster than any other shock available.

Stow it, don’t show it

OCLV Carbon Fuel EX models feature internal frame storage to stow away your tools, gear and whatever other goodies you bring on the trail. The quick-access latch is secure yet easy to use with muddy, gloved fingers.

More choices for all riders

We’ve made some major design changes to our Fuel EX line-up to ensure there’s a perfect fit for all riders. Instead of having a select few models targeted towards women, now every model has more sizes and colours for everyone.
